Presented is a concept of Information Capturing Camera which is an enhanced digital/video camera that can recognize characters in captured images, and show relevant information such as a translated version of the words in the image to another language. Discussed are technical issues and possible approaches. Technical issues include detection of the text image regions, perspective distortion normalization, binarization of character images in unknown colors, recognition of omnifont and decorative characters, word recognition, and noun compound translation. Finally, an international collaboration on the development of the required technology is proposed.
